Definitions

  • the present invention provides a solid redispersible emulsion.
  • This method is also unsuitable for encapsulating oil-in-water emulsions, since they are not adsorbed by porous materials without coalescence, and a water-soluble encapsulation material as is necessary for the release in the wash liquor is also unsuitable for the encapsulation of water-based systems.
  • compositions with controlled release which consist of nanoparticles of the active component which are in turn enclosed in a pH- or salt-sensitive microcapsule, are described by patent application U.S. 2003/0195133 A1. Like the processes already described, this method is also suitable exclusively for the encapsulation of hydrophobic water-immiscible substances but not of an aqueous emulsion.
  • a serious disadvantage in the case of the liquid fabric softeners is considered to be that large proportions of inactive components such as water, alcohols, dispersing aids or stabilizers have to be added to these dosage forms.
  • An additional factor is that the handling of the liquid fabric softeners deviates significantly from classical washing powder, which makes dosage and handling unfavorable overall.
  • An especially advantageous solid emulsion according to the present invention has been found to be one in which the emulsion component is a laundry care component and preferably a fabric softener.
  • the emulsion component is a laundry care component and preferably a fabric softener.
  • a fiber protection additive, a fragrance, a hair colorant, a hair conditioner or a composition for hair bleaching or styling is also possible.
  • polysaccharides have been found to be very advantageous, in particular those which have acid groups in free or salt form. Preference is given here especially to alginates or pectins and more preferably alginic acid, sodium alginate, potassium alginate or ammonium alginate, a low-esterification or -amidation pectin, carrageenans or mixtures thereof.
  • alginates or pectins and more preferably alginic acid, sodium alginate, potassium alginate or ammonium alginate, a low-esterification or -amidation pectin, carrageenans or mixtures thereof.
  • all water-soluble polymers which react reversibly with polyvalent metal ions with gel formation are suitable in principle.
  • the inventive solid redispersible emulsion develops its advantages especially when the shell material comprises biodegradable polysaccharides, which is likewise taken account of by the present invention.
  • a feature essential to the present invention is that the shell of the emulsion component is stabilized by polyvalent metal ions, as a result of which not only the shell but also the entire emulsion is water-insoluble.
  • Suitable polyvalent metal ions envisaged by the present invention are at least one metal ion from the group of Ca 2+ , Sr 2+ , Ba 2+ , Al 3+ , Cu 2+ and Zn 2+ . These metal ions are initially present in stable form in the shell and are not removed from the shell until in the aqueous medium and in the presence of suitable compounds capable of binding polyvalent metal ions. In the case of wash liquors, this can be done by components which are present in the washing composition.
  • the components may be water softeners such as zeolites, EDTA and salts thereof, polyphosphates, pyrophosphates, carboxymethyloxy-succinates, polyacrylates, citrates or nitrilo-triacetates.
  • water softeners such as zeolites, EDTA and salts thereof, polyphosphates, pyrophosphates, carboxymethyloxy-succinates, polyacrylates, citrates or nitrilo-triacetates.
  • the present invention also envisages that the proportion of the oil component in the solid redispersible emulsion is at least 30% by weight, preference being given to proportions of >50% by weight and especially >75% by weight, based on the overall emulsion.
  • the present invention also encompasses a process for producing it.
  • the oil component is first emulsified in water, which can optionally be done in the presence of a suitable emulsifier.
  • the emulsion from process step a) is mixed with a solution of the shell material in water.
  • the mixture obtained from process step b) is introduced into a solution which comprises the polyvalent metal ions.
  • process step a) it is also possible in process step a) to prepare a solution of the shell material in water, then, in process step b), to emulsify the oil component in the solution from process step a), optionally with addition of a suitable emulsifier, and finally, in process step c), to introduce the emulsion from process step b) into a precipitation solution comprising polyvalent metal ions.
  • process step a an emulsion of the oil component in water is prepared, optionally with addition of an emulsifier, in process step b), the shell material is dissolved in the emulsion from process step a), and, again, in process step c), the solution obtained in process step b) is introduced into the precipitation solution which comprises polyvalent metal ions.
  • the emulsion is encapsulated in a shell material which has been stabilized by incorporation of polyvalent metal ions and is insoluble in water.
  • the precipitation solutions used are solutions of di- or trivalent metal salts in water or alcohol/water mixtures.
  • Particularly suitable solutions are those of alkaline earth metal salts in water/isopropanol mixtures.
  • process step a) is to be performed in the presence of an emulsifier, it is possible in accordance with the invention to employ polysaccharides which may optionally be chemically modified. Particularly suitable in this case are hydrocolloids.
  • a further advantage of the process according to the invention is found to be that the size of the particles can be varied over a relatively wide range through the suitable selection of the process used for dropwise addition to the precipitation solution.
  • the dissolution rate can additionally also be controlled via the particle size.
  • the generation of the droplets is not limited to a particular process, which is why suitable methods from the prior art, which include atomization by an airstream, excited jet decomposition by vibrational excitation or so-called jet-cutters, can be employed as suitable.
  • the particles thus obtained from process step c) can be removed from the precipitation solution by the known processes for solid/liquid separation.
  • Representative examples here include filtration, which may optionally be performed with the aid of elevated or reduced pressure, but also sedimentation or centrifugation.
  • the solid removed can be washed before the drying, for which it is customary to use water, alcohols or suitable mixtures thereof.
  • substances which prevent conglutination of the particles to the wash solution.
  • useful substances for this purpose are surface-active substances such as phospholipids, surfactants, polysorbates or the like, but also insoluble separating agents, for example silicas.
  • the prefered apparatuses being contact dryers or fluidized bed dryers, since the low mechanical stability of the resulting particles in the still-moist state should be taken account of in any case.
  • the present invention also encompasses the use of the solid redispersible emulsion in laundry care compositions.
  • these care compositions are combined with components which are capable of binding metal ions in a liquid environment.
  • builders the release of the polyvalent metal ions stabilized in the shell material in an aqueous environment can be promoted.
  • the components of a commercial powder detergent which has been mixed, for example, with the inventive solid redispersible emulsion contribute to the release of the polyvalent metal ions fixed in the shell of the solid emulsion, as a result of which the shell itself becomes water-soluble and the initially encapsulated emulsion component is thus released into the aqueous medium in a time- and medium-dependent manner.
  • the emulsion component is a fabric softener, it can display its desired action on the textile fiber there.
